The ISL68300 is a PMBus compliant, single-phase digital DC/DC controller optimized for use with discrete MOSFETs. The ISL68300 implements the Renesas fully digital ChargeMode™ control modulation scheme, allowing it to achieve both industry leading performance and ease of use. ChargeMode control provides an inherently stable control loop that can respond to load transients in a single switching cycle, significantly decreasing output capacitor requirements. A dedicated current share bus allows for paralleling up to eight devices in a current share configuration, allowing support for a wide range of load currents. In conjunction with many other Renesas digital controllers, the ISL68300 is capable of complex sequencing and fault spreading. The Digital-DC™ (DDC) bus is a single-wire serial bus which provides high performance inter-device communication without the need for external sequencers, reducing overall system costs. The PMBus interface facilitates device configuration, provides supply telemetry and detailed fault reporting including a parametric capture tool (SnapShot). All of these features are conveniently accessible through the a href="/en/products/p

l" PowerNavigator™/a software tool. Additionally, a wide array of common configuration options are independently configurable through use of pin-strap resistors. The ISL68300 supports a comprehensive fault management system, with dedicated hardware support for cycle-by-cycle overcurrent, overvoltage, undervoltage, and temperature faults. The configurable fault response system is capable of latching off or restarting the output on a fault-by-fault basis. Integrated LDOs for device and gate driver bias allow for single supply operation. A companion device, the ISL68301, has a PWM output, which can be paired with the Renesas family of Smart Power power stages or DrMOS devices.
